' 7 Application filed July 29,

To all who-mit may concern: 7

Be it known that I, BENNETT G. J ANssoN', residing at Malden', in the county of Middlesex and State of Massachusetts, have in vented certain Improvements in \Viring- Tacks, of which the following is a speci cation. 1

The invention about to be described consists of an improved wiring tack made from a single piece of wire, preferably of steel, and of any suit-able cross-section. A piece or blank of wire has one end pointed from which extends a straight portion to the head, which consists of a series of right-angled extensions of the wire to form a flat head with depending sides, the square end of the wire terminating against the first-formed right angle. All of which I will now proceed to describe and point out specifically in the appended claim.

()f the drawings, which form a part of and illustrate the invention,,-Figure 1 is a perspective view of the wire formation of my improved tack, the insulating lining be ing omitted to more clearly show the same. Fig. 2 is a side View of the complete tack. Fig. 3 is an end View of the completed tack, and Fig. 4 is a top view of the insulating lining detached from the tack.

In the drawing 1 is a piece of iron or steel wire represented as of square cross-section having a pointed end 2, and 3 is a straight part terminating in the head 71,- it will be seen that the straight part 3 extends above the flat portion 4- 5 of the'head h and is returned upon itself, leaving a driving-end et From the end P is a short piece 6 to the right angle 7, from which is the outward tension 8 to the right angle 9, the downward extension 10 to the right angle 11, the extension 12 across to the right angle 13 not shown but opposite angle 11, the upward extension 14 to the right angle 15, the extension 16 across to the right angle 17, the downward extension 18 to the right angle 19, the cross extension 20 to the right angle 21, the upward extension 22 to the right wmrne-raox.

angle 23, and the inward, extension 2 1 whose end 25 constitutes the squared end of the wire and terminates opposite the right angle 7; thus forming a series of extensions which are spaced about as indicated by 30.

The aforesaid series of angles and extensions form the flat top 4.5 and the depending sides 31, 31, with the straight part of the wire 3 central thereof, as when the wire is returned upon itself to form the drivinghead it is brought forward to the extension 6.

I furnish an insulating lining s and sides 31, 31. made preferably from apiece of sheet fiber which is centrally perforated at 3 and its opposite sides brought up to embrace the wire, and extend under thevsides and the to and on the inside of each side 22,22; the iningis principally supported by the wire. but as it is firmly pressed into place the friction with the inner sides of the extensions helps to retain it in position.

When the tack is in use to hold conducting wires in place they are held between the top .45 and the sides 31, 31, as indicated by dotted circles in 'Fig. 2. i

I claim as my invention}- wire composed of pointed end from which the wire extends to the head where it is returned upon itself, then bent ata series of right-angled spaced extensions outward, downward, across, upward, across to the opposite side of the straight part, downward, across, upward, then toward the first angle where it terminates.

in testimony whereof, I have signed my name to this specificationin the presence of two subscribing witnesses, this 25th day of July, 1912.
